2.4GHZ Wifi band

Hi
is it possible to create just the 2.5Ghz wifi band? I am looking to control a few devices that the normal Wifi won’t reach to, the sockets are only single band

sorted with this How to disable 5G? unsure if my error but can’t see wifi after setting but trying rebuild

Do you have the PiFi USB? Or just the internal wireless?

Also, Pi 4 or Pi 5?

Internal Wifi, Pi4b rebuilt and figured out what was causing issue but then couldn’t get it to work & share the internet 2.4Ghz>wired, ended up installing Debian and configured internet sharing Using a Unifi AP on other end of cable
